To all whom it may concern: 1

Be it known that I, EDWARD vB. Hose, a citizen of the United States of America, residing in the borough of Manhattan, city, county, and State of New York, have invented certain Improvements in Typeriting Machines, of which the following is a specification.

My'inventioncomprises an improvement upon the invention dlsclosedand claimed in the patent of Lewis G. Myers No. 947,450, dated January 25, 1910, and consists ofan arrangement wherein the gage is normally out of effective position but is moved into effective position by the grasp of the oper-v ator upon the adjustable stop, thereby insuring proper adjustment of the stops, and then automatically returns, when the grasp of the operator is removed, to normal POSI- tion.

In the accompanying drawing: Figure 1 is a side elevation disclosing my improvement: Fig. 2, an end elevation showing the carriage stop rack bar in section and the stopdatch engaged with the rack: Fig. 3, a like View showing the stop latch disengaged from-the rack and the gage moved into operative relation to the center stop: Fig. 4, a view of the opposite side of Fig. 1: and Fig. 5, a plan view.

04 indicates the ordinary carriage rack bar upon which is adjustably mounted the usual movable carriage stop and 6 indicates the usual fixed orcenter stop mounted on the frame.

a is the frame of the movable stop that determines the left hand margin of the printed matter: 0?, the latch pivoted at e on this frame and whose end d engages the recesses in the rack bar. The rigld stop surface f is provided by the head of; an adjustable screw bolt mounted in the frame at the side thereof. An arrangement of such a margin stop and center stop is shown in Patent N 0. 875,430 granted December 31, 1907,t0 me which discloses the stop devices of a Royal Standard machine now well known. To

- provide a gage for setting the stop surface f the side of'the latch when it is moved to disenga e the rack, and to be then moved downward y. The part of the angular lever h be low pivot 9 extends under the frame and rack bar'sothat its extreme end i will be swung up in front of the rigid stopsurface f into position to contact withthe center stop I) when the margin stop is being adjusted. When the adjustment has been made i and latch 03 is released, the angular lever will, by gravity, fall so that its end 2' passes from between its stop surfacej and the center stop, the lever being finally arrested in the position shown in Fig. 2 by its .end it,

contacting with the under face jecti n d on the latch. I j

The characteristic feature of my-invention is that the gage is normally out of operative of the prorelation to the stop surface 1, is moved into operative relation thereto when the movable stop is adjusted on the rack'bar, and after such adjustment returns to normal inoperative position. The width of the end 2' of the gage lever corresponds with one letter space. As shown the gage is in the form of an angular lever made of sheet metal, the end h being turned at right angles to afford anenlar ed surface for contact with projection d an its opposite or gage end being likewise turned over at right angles to afford a width .equal to one letter space.

I am aware that this device'inay be embodied in a variety of forms.

It is preferred that the gage should be normally maintained in inoperative position by gravity in preference to resorting to the use of springs.

The characteristic feature of this invention is that the gage is normally out of position and it is automatically brought into gaging position when adjustment of the movable stop is made by the operator.

I claim V 1. Margin stop devices comprisinga fixed and a movable stop, a gage'normally out of operative relation to the stop surfaces of the stops and adapted to be interposed between them to adjust them a distance from each other equal to one letter space, and means for automatically effecting interposition of such gage between such surfaces when the movable stop is adjusted.

2. hlargin stop devices comprising a fixed two stoPs'but normally maintained out ofv such p'ositionby gravity and'means vfor and a movable stop, frame of the movable stop and adapted to be interposed between the 'sto butnormally withdrawn therefrom, Br,

automatically interposing the gage between such surfaces-when the'movable stop is adjustedlt- 3. Margin stop devices-comprising a fixed a gage pivoted upon the stop surfaces of the Tao bar upon which the stop frame -is mounted; a latch carriedjby the frame for means whereby on engaging and'disengaging the rack-bar and g disen agement of the latch from the; jack bar such position and means for automatically the gage between suehs'urfaces I interposing when the movable stop is adjusted.

In testimony whereof, I have hereunto 25- subscribedmy name. E EDWARD B. HESS., v a v Witnesses:
